Patent DE-2919326-A1 (DE)
Inventor: BESSON RENE
IPC: H02P8/02
Filed: 1979-05-14
Abstract: Reduces the consumption of an electronic time piece equipped with a motor 4 driving a display unit 5. A quartz oscillator 1 feeds a supply circuit 3 through a frequency divider 2. The supply circuit 3 of the motor and its control circuit 9 periodically decrease the pulse energy supplied to the motor in response to a reference signal 8.2 provided by a reference counter say every 60 seconds. The energy then supplied to the motor is regulated as a function of the presence or absence of a signal delivered by a detection switch 7 operated by the display unit. If the detection switch does not close, compensating pulses are fed to the motor to catch up the lost seconds and the pulse energy is stepped up.

Title: Self cleaning filter, esp. for drinking water - where elastic fabric dislodges solid particles collected on fine filter fabric
Inventor: SCHNEIDER GERHARD
IPC: B01D29/21
Filed: 1979-06-11
Abstract: The filter consists of a tubular grid, which is e.g. a monolithic plastic moulding with longitudinal ribs forming a circular row round the moulding. The ribs are covered by a coarse fabric mesh (I) and then a fine filter fabric (II). A liq., esp. drinking water, flows through fabric (II) first, and then through fabric (I); and the filtered water is removed from the interior of the tubular grid. Fabric (I) is elastic, and is forced inwards onto the grid by the pressure of the water being filtered. When the water is switched off, the spring in fabric (I) forces the latter outwards, thus pushing fabric (II) so particles collected on fabric (II) fall off, thus increasing the working life of the filter.

Title: Fluid mass flow metering from vibration damping - using piezoelectric vibration drive element acting also as amplitude sensor
Inventor: BINDER KURT DIPL ING DR
IPC: G01F1/28
Filed: 1979-07-14
Abstract: A fluid mass flowmeter has a vibrating obstacle in the tube in which the fluid flows. An electronic circuit evaluates the damping of the vibration due to the force exerted by the fluid. It is constructionally simpler than contentional instruments because it contains a piezoelectric rather than electrodynamic drive system which which doubles as an amplitude sensor. The use of non-linear control enables the output signal to a frequency analogue, pulse length modulated, or direct analogue voltage signal. The piezoelectric element is a flexing vibrator clamped at one end with a diaphragm plate on the other end and protected from direct flow effects by a stream lined cover. It may take one of several forms including a disc with a metal or ceramic disc attached. The electronic circuit includes a bridge with amplification and phase dependent rectification sections.

Title: Controller for a three-phase bridge circuit
Inventor: PFEIFFER ECKART PROF DR ING
IPC: H02M7/757
Filed: 1981-03-06
Abstract: In the case of a method for forming control pulses for the thyristors of a thyristor three-phase bridge, the control pulses running strictly in synchronism with the three-phase system and being capable of virtually continuously variable adjustment within a specific control range, it is intended to take into account changes in the constancy of the three-phase mains frequency for the purpose of converter control in accordance with the phase-control method. This is achieved in that the exact triggering time is derived by comparison with a time base which is produced by the three-phase mains via a control variable which is predetermined digitally at any desired times, this difference is stored in a digital timer (phase-angle timer) and the stored value is decremented to zero, a control pulse being triggered whenever the value zero is reached. <IMAGE>
